48d79d521c Better handling of AS4 optional attribute errors 
AS4 optional attribute errors were handled by session
drop (according to BGP RFC). This patch implements
error handling according to new BGP AS4 draft (*)
 - ignoring invalid AS4 optional attributes.

b807ef9a15 Fixes bug in protocol state machine 
Scheduling flush must be done before resource pool freeing as it
frees some allocated list nodes from a global list.

d6a836f8d6 Fixes core state machine. 
The core state machine was broken - it didn't free resources
in START -> DOWN transition and might freed resources after
UP -> STOP transition before protocol turned down. It leads
to deadlock on olock acquisition when lock was not freed
during previous stop.

The current behavior is that resources, allocated during
DOWN -> * transition, are freed in * -> DOWN transition,
and flushing (scheduled in UP -> *) just counteract
feeding (scheduled in * -> UP). Protocol fell down
when both flushing is done (if needed) and protocol
reports DOWN.

BTW, is thera a reason why neighbour cache item acquired
by protocol is not tracked by resource mechanism?

fbde6c3908 Fixes race condition leading to memory corruption and crash. 
When protocol started, feeding was scheduled. If protocol
got down before feeding was executed, then function
responsible for connecting protocol to kernel routing
tables was called after the function responsible for
disconnecting, then resource pool of protocol was freed,
but freed linked list structures remains in the list.

b21f68b4cd Fix bugs in OSPF MD5 authentication. First bug is that default 
values for MD5 password ID changed during reconfigure, Second
bug is that BIRD chooses password in first-fit manner, but RFC
says that it should use the one with the latest generate-from.

It also modifies the syntax for multiple passwords.
Now it is possible to just add more 'password' statements
to the interface section and it is not needed to use
'passwords' section. Old syntax can be used too.

b6bf284a90 Bugfixes in MULIT_EXIT_DISC attribute handling. 
- Old MED handling was completely different from behavior
   specified in RFCs - for example they havn't been propagated
   to neighboring areas.

 - Update tie-breaking according to RFC 4271.

 - Change default value for 'default bgp_med' configuration
   option according to RFC 4271.

98ac61766d A lot of changes: 
- metric is 3 byte long now
	- summary lsa originating
	- more OSPF areas possible
	- virtual links
	- better E1/E2 routes handling
	- some bug fixes..

I have to do:
	- md5 auth (last mandatory item from rfc2328)
	- !!!!DEBUG!!!!! (mainly virtual link system has probably a lot of bugs)
	- 2328 appendig E

13b75bacf7 protocol->import_control() could potentially call rte_cow() as well. 
AFAIK it doesn't happen in any of our protocol, but better be sure.
 2003-08-13 20:04:39 +00:00
Martin Mares
2adab6ae9c This was a potential memory leak, but not the one Feela observed. 
This one could happen when an import filter of some protocol modified
the rte (so that it would be rte_cow()ed) and later rejected it.

08f0290a1e Changed semantics of the rt_update hook. The attribute list we pass now 
contains all attributes, not just the temporary ones. This avoids having
to merge the lists inside protocols or doing searches on both of them.

Also, do filtering of routes properly. (I'd like to avoid it, but it's
needed at least in the krt protocol.)
